The first chamber is immediately vented and gas is allowed to flow around the first core and is then reintroduced to the main flow further down stream. Even though it was designed for 5.56, the bore aperture in the Helios QD is large enough in diameter to pass a 7.62mm projectile no problem.Īs far as design, ours is very unique in the industry and it actually works. You can shoot any 7.62mm projectile out of it you want to regardless of the case behind it. Due to the internal coating, the need for cleaning will be largely eliminated, though you could still easily clean our rifle silencers if you needed to. For coatings, all of our rifle silencers have an internal coating of hexagonal boron nitride which prevents fouling from sticking in the first place, and the exterior is DLC coated. Every single batch of silencer we make is inspected in a lab to ensure they meet or exceed standards for material properties each and every time. There's a lot that can go wrong with a faulty weld like the weld breaking, inconsistency, welds causing warping across the length of the silencer leading to a lack of concentricity, lack of weld penetration, weld causing a section to be out of round, in some cases negatively affecting base material properties, and our manufacturing process eliminates those issues and their byproducts entirely. How many silencers have you seen with a broken weld? How many silencers have you seen that were out of round due to a weld which caused a baffle or end cap strike? A lot. On top of that, there is no weld warping and there are no welds to break because there are no welds in the silencer. With high cooling rate, the microstructure and features of DMLS parts are very small, leading to higher strength and hardness, even when compared with forging. The DMLS process can create fully dense parts, with better material density than a billet or casting product. The additive manufacturing method we use is often stronger than billet. It is stronger and more durable than other silencers due to design, material, and construction method. The Helios QD was specifically made for shooters on 10.4" 5.56 select fire carbines to limit gas blowback to the face, and the M249. ![]() That & I prefer the Rugged/Sig QD systems to anyone else. Nearly every can has been my "perfect" can at some point - Helios has been that the longest so far, I'm just holding out to see how the CGS Helios Ti performs. To be honest, I don't own any - but have been looking INTENTLY since 2012. I hear the Sandman series is great though. Oh, and the ability to put on a to allow easier use on un-tuned ARs, other picky and difficult to tune rifles. Quite similar in length and weight to Sandman S (a bit wider in diameter, but more volume is generally a win to me). (note, the 'mount' can be used on it's own as a rudimentary FH). Will accept any QD mount with the extension tube, or at least the YHM Kurz w/ shorty brake w/out extension tube. ![]() Performs among the best of all options on 5.56 (sound and durability wise). Built for 5.56 but accommodates larger (to include. If it's going to be mounted most of the time, I'd strongly consider the CGS Helios QD (or waiting for the Helios QD Ti, if you don't have & use a full auto lower).
